Installation Notes
Install TC3704 at the front right lower position only. Verify bushing orientation, ball joint seating, and fastener torque against the vehicle service procedure before returning the vehicle to service. Because suspension components affect alignment, a professional wheel alignment is recommended after installation. Confirm fitment by year, model, and position before ordering; this part fits 2013-2019 Mercedes-Benz B250 and 2014-2019 Mercedes-Benz CLA250 in the front right lower location.
Quality Assurance
Delphi tests suspension and steering components under extreme temperature and corrosion conditions, including sub-zero and high-heat exposure plus extended salt-spray testing, to support OE-level durability expectations in aftermarket service.
